You can write and read direct from the I/O Adress in the program and transfer the values you need. DPRD_DAT / DPWR_Dat should be use for Data > 4byte for a consistence data transfer, this also depend on which PLC you use. What you mean with "No cyclic comm"? Warning 8526? If yes check the name of the devices and the IP that it matches the configured data from HWConfig. Any RED LED on ? Regards Christoph

For the program: You say you would not use any preconfigured FB, so you must complete implement you own logic depend on the drive documentation. In the list manual you find the Control sequence for the Drive Control and Status Word, this must then be implemented from you side complete! Why we should write you program? Regards Christoph

Ladder Programs you can download here: https://support.industry.siemens.com/cs/ww/en/view/109475044 A sample application you can find here: https://support.industry.siemens.com/cs/ww/en/view/60140921 https://support.industry.siemens.com/cs/ww/en/view/61450312 Regards Christoph
